Description

The present invention relates to a patterned structure of a patterned tableware, a patterned tableware having this patterned structure, and a spoon having this patterned structure.

In recent years, patterned instruments such as spoons that can be disposed of after use have been widely used from the viewpoint of hygiene. Many of these disposable patterned appliances are made of cardboard rather than plastic molded products in consideration of environmental issues.

For example, an assembling measuring spoon has been proposed as a patterned instrument molded from a single piece of cardboard (Patent Document 1). The entire measuring spoon is made of flat plate-shaped cardboard, and by folding and assembling this cardboard, it becomes a three-dimensional spoon. And since it is made of cardboard, it can be easily disposed of after use.

By the way, in general, a cardboard-molded instrument with a handle, for example, a cardboard-molded spoon, when trying to scoop an object of a certain weight or more, the handle part cannot withstand the weight of the object and bends. There was a risk that it would end up. Therefore, it is very important that the handle portion has sufficient strength to withstand the weight of the object scooped by the spoon.

Therefore, in the measuring spoon described above, the grip portion corresponding to the handle of the spoon is composed of a side plate made of a pair of thick papers that are folded and overlapped. The pair of side plates are folded upward in a valley fold with the bent portion arranged below as an axis, and are closely overlapped with each other without any gap. Therefore, in the grip portion, sufficient strength is secured against the force of bending the grip portion in the vertical direction due to the rigidity of the stacked thick papers.

However, since the above-mentioned grip portion is a stack of a pair of side plates, when using a spoon, the user must pinch the grip portion or hold the entire grip portion. , It was very difficult to use.

Further, for example, in the same structure as the above-mentioned grip portion, among the commercially available spoons for eating and drinking molded from thick paper, the grip portion is composed of a pair of side plates bent into a substantially V shape. exist. In a spoon provided with such a grip portion, if the user loosens the force for gripping the grip portion when using the spoon, the pair of side plates may open due to the rigidity of the thick paper. Then, in order to continue using the grip while maintaining a certain strength, the user must always be careful not to open the pair of side plates.

Further, when using a spoon for eating and drinking, the user usually grips the grip portion of the spoon, that is, the handle portion in the same way as a writing instrument such as a pencil. However, with the measuring spoon or a spoon whose grip is composed of a pair of substantially V-shaped side plates, it is difficult to grip the grip in the same way as a writing tool, and the structure of the handle is for eating and drinking. It was very difficult to handle as a spoon. Therefore, there is a demand for a patterned tableware structure that is easy for the user to grasp.

In the present embodiment, the pattern structure of the patterned tableware (hereinafter, simply referred to as “pattern structure”) will be described by taking a spoon 1 which is a patterned tableware having the pattern structure 10 shown in FIGS. 1 to 4 as an example. .. In the following description, the longitudinal direction of the spoon 1 is defined as the front-rear direction X, and the direction horizontally orthogonal to the front-rear direction X is defined as the left-right direction Y. Then, the vertical direction orthogonal to the front-rear direction X and the left-right direction Y is defined as the vertical direction Z.

As shown in FIG. 1, the spoon 1 can be assembled from a blank 2 which is a sheet member formed by punching a thick paper into a predetermined shape. In the blank 2, the front-back direction X is the longitudinal direction of the spoon 1, the front side is the tip 1a side of the spoon 1, and the rear side is the handle end 1b side of the spoon 1. The blank 2 is connected to a bottom portion 4 extending along the front-rear direction X to form the bottom surface of the handle 3 of the spoon 1 and both ends in the lateral direction of the bottom portion 4, that is, both ends in the left-right direction Y, and the handle 3 is connected. A pair of side surface portions 5 constituting the side surfaces of the above, an upper surface portion 6 connected to one of the pair of side surface portions 5 to form an upper surface of the handle 3, and a bottom portion 4 and a side surface portion 5 along the front-rear direction X. It extends forward and is composed of a pot portion 7 constituting the pot 1c of the spoon 1.

The bottom portion 4, the side surface portion 5, the upper surface portion 6 and the pot portion 7 are integrally molded in the blank 2, and the bottom portion 4, the side surface portion 5 and the pot portion 7 are molded substantially symmetrically except for the top surface portion 6. Has been done. In this embodiment, a blank 2 molded from thick paper is shown as an example, but the blank 2 can be bent by a user of the spoon 1 (not shown), for example, a sheet member made of synthetic resin. Various sheet members can be used as long as the sheet members have a certain rigidity as high as that of thick paper.

The bottom portion 4 is a substantially linear flat plate-shaped portion formed substantially in the center of the blank 2 in the left-right direction Y. Both ends of the bottom portion 4 in the left-right direction Y are sandwiched between a pair of side surface portions 5, and form the bottom surface of the pot 1c and the handle 3 in the spoon 1 (FIG. 2). Therefore, the bottom portion 4 extends from the tip 1a to the handle end 1b through the pot portion 7 in the blank 2. At this time, the bottom portion 4 is formed so that the width of the pot portion 7 in the left-right direction Y is wider than that of the other portions. On the other hand, on the rear side of the pot portion 7, it is narrowed in a tapered shape and formed narrowly, and the bottom portion 4 of this narrow width is formed from the rear end of the pot portion 7 to the buttock 1b.

The side surface portion 5 is a pair of flat plate-shaped portions that are connected to both ends of the bottom portion 4 in the lateral direction, that is, both ends in the left-right direction Y and extend along the front-rear direction X. The side surface portion 5 is composed of a first side surface portion 5a connected to the left end portion of the bottom portion 4 and a second side surface portion 5b connected to the right end portion of the bottom portion 4. The connecting portion between the bottom portion 4 and the first side surface portion 5a is the first connecting portion 11, and the connecting portion between the bottom portion 4 and the second side surface portion 5b is the second connecting portion 12. The first side surface portion 5a and the second side surface portion 5b are configured to be bendable in a valley fold with respect to the bottom portion 4 at each of the first connecting portion 11 and the second connecting portion 12. The first side surface portion 5a and the second side surface portion 5b are bent in a valley fold with respect to the bottom portion 4 so as to face each other and form the side surface of the handle 3 (FIG. 2). Further, a valley fold line 14 described later is formed in the first connecting portion 11 and the second connecting portion 12 (FIG. 3A).

The first side surface portion 5a and the second side surface portion 5b form the side surfaces of the pot 1c and the handle 3 in the spoon 1. Therefore, similarly to the bottom portion 4, in the blank 2, the blank 2 extends from the tip 1a through the pot portion 7 to the handle end 1b. Further, in the first side surface portion 5a and the second side surface portion 5b, in the pot portion 7, the first side surface portion 5a is formed in an arc shape in which the first side surface portion 5a bulges toward the left, and the second side surface portion 5b bulges toward the right direction. It is formed in an arc shape. As a result, in the assembled spoon 1, a pot 1c having a curved outer edge is formed. Further, the arc-shaped portions of the first side surface portion 5a and the second side surface portion 5b are punched out in a fine wavy shape at their ends.

An upper surface portion 6 is connected to the first side surface portion 5a.
In the left-right direction Y, the upper surface portion 6 has a right end 6a at one end opposite to the side of the first side surface portion 5a to which the bottom portion 4 is connected, that is, the left end portion of the first side surface portion 5a. It is a plate-like part connected to. The connecting portion between the first side surface portion 5a and the upper surface portion 6 is the third connecting portion 13, and the valley fold line 14 described later is also formed in the third connecting portion 13 (FIG. 3A).

The upper surface portion 6 is configured to be bendable in a valley fold with respect to the first side surface portion 5a in the third connecting portion 13. Then, in the bent upper surface portion 6, the left end 6b, which is the other end of the upper surface portion 6, is locked to the second side surface portion 5b. Specifically, the left end 6b of the upper surface portion 6 is locked to the side opposite to the side to which the bottom portion 4 of the second side surface portion 5b is connected, that is, the right end portion of the second side surface portion 5b.

Further, a widening portion 6c formed as a free end is formed at the left end 6b of the upper surface portion 6. The widening portion 6c is locked to the locking portion 8 formed at the right end portion of the second side surface portion 5b. The widened portion 6c is formed so that both ends of the front-rear direction X at the left end 6b project forward and backward as compared with the other portions of the upper surface portion 6. The portions protruding forward and backward are convex portions 6d, which are R-processed. In the portion of the upper surface portion 6 other than the widening portion 6c, the width of the front-rear direction X on the right end 6a side is slightly narrower than the width of the front-rear direction X on the widening base portion 6e side, which is the base of the widening portion 6c, and is on the right side. It is formed in a tapered shape toward the direction.

The locking portion 8 is a concavely open portion formed at the right end portion of the second side surface portion 5b. Specifically, the locking portion 8 is formed by cutting a part of the second side surface portion 5b toward the left side in a substantially trapezoidal shape at the right end portion of the second side surface portion 5b. At this time, the locking portion 8 is cut out in a substantially trapezoidal shape with the left side of the second side surface portion 5b as the lower bottom and the right side as the upper bottom shorter than the lower bottom. Therefore, the locking portion 8 is composed of an opening 8a that narrows and opens in a tapered shape toward the right side, and a locking piece 8b formed at the front end and the rear end of the opening 8a. Further, the locking piece 8b on the rear side projects slightly larger than the locking piece 8b on the front side, and a mountain fold line 15 is formed at the base thereof (FIG. 3A). Therefore, the locking piece 8b on the rear side can be easily folded into a mountain fold with respect to the second side surface portion 5b along the mountain fold line 15.

The mountain fold line 15 is a ruled line or a streak provided on the surface of the blank 2, and is formed by cutting or cutting the surface of the blank 2 or embossing the surface of the blank 2. In the present embodiment, the mountain fold line 15 is formed by cutting the surface of the blank 2. As a method of making this cut, a crease cut, a half cut or a half cut in which the blank 2 is cut to a predetermined depth is used.

It can be folded into a mountain fold for each of 5b.
In the blank 2, the finger resting piece 5c on the right side is integrally formed with the locking piece 8b on the rear side.
Further, in the present embodiment, the blank 2 in which the finger resting piece 5c is formed on the first side surface portion 5a and the second side surface portion 5b is shown as an example, but the blank is one in which the finger resting piece 5c is not formed. Further, the finger resting piece 5c on the right side and the locking piece 8b on the rear side may not be integrally formed, but may be formed separately.

The opening 8a is formed so that the length D1 of the opening base 8c, which is the base thereof, is longer than the length D2 of the front-rear direction X in the portion other than the widening portion 6c of the upper surface portion 6. Therefore, a portion other than the widening portion 6c of the upper surface portion 6 can be inserted into the opening portion 8a. Further, the length D1 of the opening base portion 8c is formed shorter than the length D3 of the widening portion 6c in the front-rear direction X. Therefore, the left end 6b of the upper surface portion 6 is locked to the second side surface portion 5b by hooking the convex portion 6d to the locking piece 8b while the portion other than the widening portion 6c of the upper surface portion 6 is inserted into the opening portion 8a. can do.

Further, the upper surface portion 6 is formed so that the length D4 in the left-right direction Y from the right end 6a to the widening base portion 6e is longer than the length D5 in the left-right direction Y of the bottom portion 4 in the handle 3 portion. Therefore, when the upper surface portion 6 is bridged between the bent first side surface portion 5a and the second side surface portion 5b, and the left end 6b of the upper surface portion 6 is locked to the locking portion 8 of the second side surface portion 5b. The first side surface portion 5a and the second side surface portion 5b locked by the upper surface portion 6 are locked in a state where the upper surface portion 6 side is more open than the bottom portion 4 side (FIGS. 2 and 3 (b)).

In the blank 2, as shown in FIG. 3A, a valley fold line 14 is formed in the first connecting portion 11, the second connecting portion 12, and the third connecting portion 13. Therefore, as shown in FIG. 3B, the first side surface portion 5a and the second side surface portion 5b can be easily folded in a valley fold with respect to the bottom portion 4 along the valley fold line 14. Similarly, the upper surface portion 6 can be easily folded in a valley fold with respect to the first side surface portion 5a along the valley fold line 14.
The valley fold line 14 is a ruled line or a streak provided on the surface of the blank 2 like the mountain fold line 15, and the surface of the blank 2 is cut out or cut, or the surface of the blank 2 is embossed. Is formed by doing. In the present embodiment, the valley fold line 14 is formed by cutting the surface of the blank 2. As a method of making this cut, a crease cut, a half cut or a half cut in which the blank 2 is cut to a predetermined depth is used.

Further, in the blank 2, as shown in FIGS. 1 and 3A, in the left-right direction Y, the length D6 from the first connecting portion 11 to the third connecting portion 13 in the first side surface portion 5a and the second The length D7 from the second connecting portion 12 on the side surface portion 5b to the opening base portion 8c of the locking portion 8 is configured to have the same length. Therefore, when the upper surface portion 6 is bridged between the first side surface portion 5a and the second side surface portion 5b bent in a valley fold with respect to the bottom portion 4, the upper surface portion 6 and the bottom portion 4 become substantially parallel. As a result, the cross section of the handle 3 has a substantially trapezoidal shape in which the upper surface portion 6 and the bottom portion 4 are substantially parallel to each other and the upper surface portion 6 side is wider than the bottom portion 4 side (FIG. 3 (b)).

The pot portion 7 is formed by a bottom portion 4, a first side surface portion 5a, and a second side surface portion 5b extending toward the front in the front-rear direction X, and constitutes the pot 1c of the spoon 1 (FIGS. 1 and 2). ). Further, in the pot portion 7, the valley fold lines 14 formed in the first connecting portion 11 and the second connecting portion 12 extend along the shape of the bottom portion 4 to the vicinity of the tip 1a. Therefore, when the first side surface portion 5a and the second side surface portion 5b are bent in a valley fold with respect to the bottom portion 4, the first side surface portion 5a and the second side surface portion 5b are also folded along the valley fold line 14 in the pot portion 7. It is bent to form a three-dimensional pot 1c (FIG. 2). The valley fold line 14 in the pot portion 7 is formed by embossing the surface of the blank 2.

In the present embodiment, the spoon 1 has been described as an example of the patterned tableware having the handle structure 10, but the patterned tableware having the handle structure 10 is not limited to the spoon 1, and the shaped pot 1c of the pot portion 7 is used. It is not limited to what constitutes. Therefore, the handle structure 10 can also be used for patterned tableware other than spoons. For example, instead of the pot 1c, it can be used for various patterned tableware such as a fork type or a knife type depending on the purpose.

Next, a method of assembling the spoon 1 of the present embodiment will be described.
First, in the flat plate-shaped blank 2, the first side surface portion 5a is bent in a valley fold with respect to the bottom portion 4 with the first connecting portion 11 as an axis. Subsequently, the second side surface portion 5b is bent in a valley fold with respect to the bottom portion 4 with the second connecting portion 12 as an axis. At this time, in the acupuncture point portion 7, the acupuncture point portion 7 is bent along the valley fold line 14 along with the bending of the first side surface portion 5a and the second side surface portion 5b to form the acupuncture point 1c. Next, the upper surface portion 6 is bent in a valley fold with respect to the first side surface portion 5a with the third connecting portion 13 as an axis.

Then, in a state where the bent first side surface portion 5a and the second side surface portion 5b are narrowed so as to overlap each other, the portion other than the widening portion 6c on the upper surface portion 6 is inserted into the opening portion 8a of the locking portion 8, and then the second side surface portion 8a is inserted. 1 The side surface portion 5a and the second side surface portion 5b are opened. Then, the first side surface portion 5a and the second side surface portion 5b are opened by the rigidity of the thick paper, so that the convex portion 6d of the widening portion 6c is caught by the locking piece 8b of the locking portion 8. As a result, the left end 6b of the upper surface portion 6 is locked to the second side surface portion 5b, and the first side surface portion 5a and the first side surface portion 5a and the upper surface portion 6 bridged between the first side surface portion 5a and the second side surface portion 5b. The second side surface portion 5b is locked. Then, the first side surface portion 5a and the second side surface portion 5b are maintained in a bent state against the rigidity of the blank 2. In this way, the spoon 1 having the handle structure 10 is assembled.

Further, in the assembled spoon 1, as shown in FIG. 4, the locking piece 8b on the rear side is folded in a mountain fold with respect to the second side surface portion 5b along the mountain fold line 15, and the rear side is folded. It can be overlapped with the convex portion 6d of. As a result, the engagement between the locking piece 8b and the convex portion 6d can be made stronger. Further, the finger resting pieces 5c provided in pairs on the left and right may be bent in a mountain fold with respect to each of the first side surface portion 5a and the second side surface portion 5b. As a result, the bent finger rest piece 5c becomes a pair of finger rests that project substantially horizontally toward the outside in the left-right direction Y.
As shown in FIG. 2, the spoon 1 can also be used in a state where the finger resting piece 5c and the locking piece 8b on the rear side are not bent.

Next, the effect of the handle structure 10 according to the present embodiment will be described.
The handle structure 10 has a bottom portion 4, a first side surface portion 5a, a second side surface portion 5b, and an upper surface portion 6. Then, the first side surface portion 5a and the second side surface portion 5b locked by the upper surface portion 6 are in a state where the upper surface portion 6 side is more open than the bottom portion 4 side and is bent against the rigidity of the thick paper. Be maintained. Therefore, the handle 3 composed of the bottom portion 4, the first side surface portion 5a, the second side surface portion 5b, and the upper surface portion 6 has a substantially trapezoidal three-dimensional shape in a cross section cut in the longitudinal direction thereof (FIG. 3 (FIG. 3). b)). Therefore, since the user can grip the handle 3 in the same way as a writing tool, it is particularly easy to grip when eating or drinking. Further, since the upper surface portion 6 allows the user's thumb to be placed on the upper surface portion 6 when gripping in the same manner as a writing tool, the user can stably grip the handle 3. can.

Further, since the handle 3 has a three-dimensional shape having a substantially trapezoidal cross section, it is difficult to bend with respect to the upper surface portion 6 side or the bottom portion 4 side, and sufficient strength can be secured. Such a three-dimensional cross-sectional shape of the handle 3 is important for maintaining the strength of the handle 3, and for example, the same effect can be obtained even when the cross section of the handle 3 is substantially triangular. .. When the cross section of the handle 3 has a substantially triangular shape, the bottom portion 4 is configured as a straight portion instead of a flat portion. By doing so, the cross section of the handle 3 becomes a substantially triangular shape mainly composed of the first side surface portion, the second side surface portion, and the upper surface portion.

Further, the handle structure 10 is maintained in a state in which the first side surface portion 5a and the second side surface portion 5b are bent against the rigidity of the thick paper. Therefore, due to the force that the first side surface portion 5a and the second side surface portion 5b try to open, the bottom portion 4, the first side surface portion 5a, the second side surface portion 5b, and the upper surface portion 6 constituting the handle 3 have the handle 3 The elastic force always acts from the inside to the outside in the cross section. Then, the cross section of the handle 3 does not easily lose its shape due to its substantially trapezoidal shape, and the fixed feeling of the handle 3 becomes stable. Therefore, the user can stably grip the handle 3.

In the handle structure 10, the left end 6b of the upper surface portion 6 is connected to the end portion of the first side surface portion 5a opposite to the side to which the bottom portion 4 is connected. Then, the upper surface portion 6 is bent in a valley fold with respect to the first side surface portion 5a, and the right end 6a of the upper surface portion 6 is locked to the second side surface portion 5b. Therefore, the bottom portion 4, the first side surface portion 5a, the second side surface portion 5b, and the top surface portion 6 constituting the handle 3 are all composed of a blank 2 which is one thick paper, and the handle 3 is simply bent. Can be easily assembled. Further, the first side surface portion 5a and the second side surface portion 5b can be easily locked by the upper surface portion 6.

The handle structure 10 includes a locking portion 8 formed by cutting out the second side surface portion 5b at an end portion opposite to the side to which the bottom portion 4 is connected, and the locking portion 8 is provided. A locking piece 8b is formed in the portion 8. A widening portion 6c that can be hooked on the locking piece 8b and locked is formed at the left end 6b of the upper surface portion 6. Therefore, the first side surface portion 5a and the second side surface portion 5b can be locked by the upper surface portion 6 only by hooking the widening portion 6c on the locking piece 8b. Therefore, the handle 3 is easy to assemble.

Further, in the handle structure 10, in a state where the widening portion 6c is locked to the locking piece 8b, the locking piece 8b can be folded into a mountain fold with respect to the second side surface portion 5b and overlapped with the widening portion 6c. .. As a result, it is possible to prevent the widening portion 6c from coming off from the locking piece 8b, and it is possible to further strengthen the locking between the left end 6b of the upper surface portion 6 and the second side surface portion 5b.
Further, in this case, since the locking piece 8b protruding upward is in a state of being bent and overlapped with the widening portion 6c, the user is compared with the case where the locking piece 8b is not bent. The shape of the handle 3 is easier to grip. Further, even when viewed upward, the convex portion 6d is hidden behind the locking piece 8b, and neither the locking piece 8b on the rear side nor the convex portion 6d is in a protruding state, so that the user can easily grip the convex portion 6d. It becomes the shape of the handle 3. Further, since the right end of the bent rear locking piece 8b and the left end 6b of the upper surface portion 6 locked to the second side surface portion 5b partially overlap with each other, the left end 6b of the upper surface portion 6 to the handle tail 1b The shape is smooth, and the user can grip the handle 3 without any discomfort.

The handle structure 10 has a bottom portion 4 formed of a flat surface. Therefore, the cross section of the handle 3 composed of the bottom portion 4, the first side surface portion 5a, the second side surface portion 5b, and the top surface portion 6 has a substantially trapezoidal shape. Therefore, it is easy for the user to grip the handle 3.
Further, since the blank 2 of the handle structure 10 is made of thick paper, it is easy for the user to assemble and can be easily disposed of in consideration of environmental problems.

In the handle structure 10, valley fold lines 14 are formed in the first connecting portion 11, the second connecting portion 12, and the third connecting portion 13. The valley fold line 14 is formed by cutting the surface of the blank 2 on the side to be folded into the valley fold (FIG. 3A). Therefore, in the first connecting portion 11 and the second connecting portion 12, the first side surface portion 5a and the second side surface portion 5b bent in a valley fold with respect to the bottom portion 4 are pressed against the bottom portion 4, respectively (FIG. 3 (b). )). Then, in the first connecting portion 11 and the second connecting portion 12, the elastic force in the direction in which the first side surface portion 5a, the second side surface portion 5b, and the bottom portion 4 are opened to each other always acts. Similarly, in the third connecting portion 13, the upper surface portion 6 bent in a valley fold with respect to the first side surface portion 5a is pressed against the first side surface portion 5a. Then, in the third connecting portion 13, the elastic force in the direction in which the first side surface portion 5a and the upper surface portion 6 are opened to each other always acts. By the action of these elastic forces, the substantially trapezoidal shape in the cross section of the handle 3 is less likely to lose its shape, and the fixed feeling of the handle 3 becomes more stable.
Further, since the valley fold line 14 is formed, the user can accurately and easily bend the first side surface portion 5a, the second side surface portion 5b, and the upper surface portion 6 when assembling the spoon 1. be able to.

The handle structure 10 has a finger resting piece 5c in which each of the first side surface portion 5a and the second side surface portion 5b projects from an end portion opposite to the side connected to the bottom portion 4. The finger resting piece 5c can be folded into a mountain fold with respect to each of the first side surface portion 5a and the second side surface portion 5b. Therefore, the bent finger rest piece 5c can be used as a pair of finger rests that project substantially horizontally toward the outside in the left-right direction Y. Therefore, the user can hold the handle 3 by placing his / her thumb on the finger resting piece 5c in addition to the upper surface portion 6, so that the usability is improved.
In particular, in the handle structure 10, when the handle 3 is gripped by the user, the bottom portion 4 is sandwiched between the index finger and the middle finger, and the upper surface portion 6 is pressed by the thumb. In this case, for example, in the spoon 1 provided with the handle structure 10, when the pot 1c is carried to the user's mouth, the pot 1c is horizontal so that the object scooped by the pot 1c does not spill. It is important that the sauce is carried to the mouth while being maintained. However, if the user tries to carry the pot 1c to the mouth while keeping the pot 1c horizontal with the thumb placed on the upper surface portion 6, it is necessary to strongly twist the wrist or raise the elbow. This is an unnatural movement that does not occur with a regular spoon. Therefore, when the user carries the pot 1c to the mouth, the thumb is slid backward from the upper surface portion 6, the thumb is placed on the finger resting piece 5c, and the spoon 1 is pressed, so that the wrist is easily twisted and the pot is easily twisted. It becomes easier to carry 1c to the mouth. Therefore, the usability of the handle 3 is improved, and a usability comparable to that of a normal spoon can be obtained. Further, in the handle structure 10, since the upper surface portion 6 and the finger resting piece 5c are substantially on the same plane, it is easy to slide the thumb between the upper surface portion 6 and the finger resting piece 5c.

The spoon 1 provided with the handle structure 10 has the same effect as the handle structure 10 described above, and has the first side surface portion 5a and the second side surface portion 5b along the first connecting portion 11 and the second connecting portion 12, respectively. By bending the spoon 1, the pot 1c of the spoon 1 can be formed at the same time. Therefore, it is easy for the user to assemble.

Further, in the handle structure 10, the spoon 1 is assembled from a blank 2 composed of one cardboard. Therefore, it is possible to provide a spoon 1 which can be transported and stored in a small space and is excellent in cost and disposal. In addition, this spoon 1 is easy to assemble and disassemble.
